Solid Roller Lifters for the street with no lash adjustments?

[KMS]

I was researching solid rollers on the "other" site, and came across this.. it seemed to fizle out too fast for what it was.

Does this have any merit? They seem to be limited on spring pressure, but allow solid rollers to be run on the street without all the maintenance.

Now available from Morel is the Perfect Roller lifter. . .runs on a hydraulic roller or a SOLID roller lobe profile. After months of Spintron testing, live engine testing and field testing a new lifter is available to the enthusiast. Morel has taken its technology in materials and body design of solid roller lifters and built the ultimate hydraulic roller. This lifter features an upgraded body, roller and axle. The stainless tie bar is connected to a 3 button system to prevent binding and premature failure. The valving system has been tweaked to prevent valve float to a tested 7300 rpm. Last but not least, the bodies are REM finished. In back to back testing in a BBC application, this lifter proved to make 34 more HP over a std hydraulic roller lifter and an increase in additional rpm when used on the same cam profile.

The lifters when used on solid roller cams do have their limits. Spring pressures should be a max of 220# on the seat and 550# open pressure.

This new generation of lifter is recommended for severe street strip use and extended marine applications. You can now have you Solid roller and no lash adjustment.....

These are available in drop in for the LS1 or Tie bar including the Warhawk block. They will also be available in .903" diameter.

Are these usable with non-adjustable rockers like Harland Sharp stock style replacements?

this lifter is designed for Zero pre-load. Someone who is knowledgeable about valve adjustment yes could use non adjustable rockers.
